JSON to YAML

What Is a JSON to YAML Converter?

A JSON to YAML converter rewrites JSON as YAML. Both formats store the same kinds of data, but YAML uses indentation instead of braces and quotes, which many people find easier to read. YAML is widely used for configuration files, Kubernetes manifests, and CI/CD pipelines.

ToolsViewer's online JSON to YAML tool converts your JSON in the browser and gives you detailed control over how the YAML is written.

How to Use the JSON to YAML Converter

Step 1: Add your JSON
Paste JSON, import a .json or .txt file, fetch a public URL, or load the sample.

Step 2: Adjust the YAML options
Choose the indentation, style, line width, and quote type, and turn on any extra options you need.

Step 3: Click Convert
The tool converts your JSON to YAML using your settings.

Step 4: Copy or download
Copy the YAML or download it with the file extension you prefer.
